The Impact of an ERP System on Maintenance

For over two decades, ERP systems have dominated management, but their implementation in maintenance departments has serious side effects. Expanding functionality beyond the MRP II standard has significantly increased their complexity. This, in turn, significantly complicates their operation. Instead of simplifying work, the complex software structure often paralyzes daily operations.

Analyses show that in some implementations, as much as 50% of the team’s processes are assigned to tasks outside of strict maintenance, transforming engineers into administrative staff and significantly impacting the technical efficiency of the entire facility. As a result, instead of improving efficiency, companies struggle with a decline in actual staff productivity.

Complexity and administrative barriers

The ERP system requires the continuous monitoring and entry of as many as 14 separate data sets—from spare parts specifications to detailed operational costs. The requirement to record all events online is essential for calculating metrics like OEE , but for smaller companies, the entire procedure presents an insurmountable barrier.

Mechanics waste valuable time on bureaucracy instead of focusing on resolving breakdowns that last from 10 minutes to as long as 10 days . As if that weren’t enough, the system’s top-down strategy allocates only 20% of total staff time to resolving these unforeseen faults .

Rigid division of working time

The software also enforces an artificial organizational framework , completely ignoring the specifics of technical department work. The system’s strategy often divides staff time into rigid blocks:

• 30% – production of special equipment,
• 30% – major renovations,
• 20% – retooling,
• 20% – unforeseen failures.

This approach completely destroys flexibility. The system fails to account for the fact that failures are purely random events. Therefore, imposing a rigorous schedule in ERP leads to absurd resource conflicts, drastically hindering the ability to respond to ongoing crises and machine failures.

Does the evaluation system take into account employee absenteeism?

Automating incentive systems in ERP breeds unhealthy competition and imposes pressure on employees. The algorithm calculates bonuses, often introducing unfair rules. The maximum bonus pool is 800 points based on an ideal workload (8 hours over 5 days).

The biggest drawback of this automated evaluation mechanism is its complete failure to account for employee absenteeism. As a result, the system directly penalizes sickness, undermining the trust and motivation of the entire technical team.

Costs outweigh effectiveness

Implementing advanced ERP systems significantly consumes resources that rarely pay off in maintenance. The complexity of changeover matrices and planning procedures generates significant maintenance costs. Companies pay a fortune for features that, instead of providing support, only overwhelm staff with unnecessary administration. Consequently, the actual efficiency of their machinery decreases. The company thus suffers double losses: on the one hand, expensive software maintenance, and on the other, technical delays resulting from cumbersome ERP procedures.

Is system bureaucracy overwhelming technicians?

Every technical intervention, even the smallest, must undergo the six-stage order lifecycle imposed by the ERP software : from initiation, through planning and confirmation, to commencement, completion, and deletion. The system requires the completion of as many as 10 detailed data categories, such as priorities, tools used, statuses, and costs.

This requirement significantly complicates routine repairs. Instead of responding quickly to equipment problems on the shop floor, maintenance workers must navigate a maze of digital approvals. This dramatically increases response times and distracts engineers from their real, physical responsibilities.

How do ERP algorithms falsify performance evaluation?

The software evaluates based on rigid metrics, completely ignoring the technical context. The algorithm calculates the machine’s changeover time as a percentage of total operating time . If this metric is between 0% and 20%, the system awards a maximum score of 5 points. However, if difficulties extend this time beyond 60%, the employee automatically receives 0 points.

The algorithm fails to account for objective complications, for example, on the 5th, 6th, and 7th days of work analyzed. Such a mechanical evaluation has a demotivating effect on the entire staff.

Do rigid ERP algorithms ultimately destroy efficiency?

Full software integration, which forces the unconditional execution of a generated master production plan , leads to technical paralysis. Instead of immediately repairing the machine, engineers waste time on:

• entering causes from a closed list of symptoms,
• waiting for email notifications from the dispatcher,
• specifying the demand for parts in the ERP database.

Ultimately, ERP completely strips the technical department of its flexibility, which impacts the reliability and operational fluidity of the plant.
